Product information "Odot BT-3804 – 4 thermocouple inputs (J/K/E/T/S/R/B/N/C), B series"

Measure temperatures directly in the BOXIO, without transmitters in front: the temperature cards of the Odot B series take resistance thermometers and thermocouples directly, for example on furnaces, heating circuits, cooling water or plastics machinery.

🏭 Typical uses

  • Pt100 in 2- or 3-wire connection: BT-3714 with 4 inputs, 15 bit, accuracy 0.5 °C.
  • Pt1000: BT-3724 with 4 inputs, 15 bit, accuracy 0.5 °C.
  • Pt100 with channel isolation: BT-3734 with 4 inputs, 16 bit, 2- or 3-wire, channels isolated from each other.
  • Thermocouples up to high temperatures: BT-3804 with 4 inputs for type J, K, E, T, S, R, B, N and C, 24-bit converter, ±0.3 % of full scale at 25 °C, TVS surge protection.

🔌 Works with

  • Odot B2341 PLC (CODESYS 3.5)
  • Odot BN bus couplers – PROFINET, EtherCAT, EtherNet/IP, Modbus TCP/RTU, CANopen
  • BOXIO housing B32 (2 cards) or B64 (4 cards)

📐 Common data

  • Diagnostics per channel: wire break, over- and underrange (Pt cards also short circuit)
  • Unused channels can be disabled, which shortens the sampling time
  • Galvanically isolated from the internal bus (2.5 kV rms), push-in terminals up to 1 mm² (AWG 18)
  • Operation −30 °C to +75 °C (BT-3714, BT-3724, BT-3804), IP20

Important: The cards only work inside a B32 or B64 BOXIO housing, together with a BN bus coupler or the B2341 PLC. Cover empty slots with the SH847-3 slot cover.
